A hat-trick or hat trick in sport is the achievement of a positive feat three times during a game, or other achievements based on threes.
623B ~ 623B ~ RCC A+B ~ B!E! ~ 4B = 21 hits, 111 damage (more damage if clean hit).
This combo is so godlike that it deserves its own thread. Basically you have to get lucky 3 times in a row, while at the same time executing insane input skill with RCC A+B and B!E!.
First 623B - get lucky (#1) and don't have it go into PB.
Second 623B - get lucky (#2) and don't have it go into PB.
RCC A+B - Execute with precision and get lucky (#3, hat trick!) and don't have it go into the spin.
B!E! - Execute with extreme precision, chance of clean hit.
4B - Sigh of relief for successfully landing the combo. Pat yourself on the back.
I wouldn't be surprised if this is the hardest combo in the game!
Dampierre also has another "Hat Trick Combo", but this one is a little bit easier to do in training mode, but perhaps more difficult to land in the midst of combat because of the luck required to have B+K hit:
B+K ~ 623B ~ RCC A+B ~ B!E! ~ 4B = 90 dmg
